Skip to main content Module util Copy item path Source adler32 Adler-32 checksums (RFC 1950, https://www.rfc-editor.org/rfc/rfc1950.html ). crypto_helper The symmetric crypto used in Steam’s protocols. date_utils Converting between Unix timestamps and SystemTime debug_log The global debug log. Listeners are either trait objects or plain functions,
and messages are also sent on a broadcast channel for anyone who’d rather
subscribe. debug_network_listener Dumping network messages to disk for debugging. hardware_utils The machine identity Steam uses to recognize a machine, sent with the logon
as a MessageObject. i_log_context Writing to the debug log on behalf of a client. key_dictionary Steam’s public key for each EUniverseSubjectPublicKeyInfo structures; a single wrong byte breaks the channel
encryption handshake. lzma lzma_decoder A small, allocation-free LZMA decoder for raw streams whose uncompressed size
is known up front. The output buffer doubles as the dictionary, so the whole
thing is decoded in one call. lzma_util Decoding blobs that start with the “LZMA” magic header. mac_helpers macOS helpers for the machine id: the platform serial number and the boot
disk’s media UUID. msg_util The protobuf flag on message numbers. net_helpers IP address and endpoint helpers. scheduled_function A function that runs on a fixed schedule (immediately, then every delay),
on a tokio task. Stopping it cancels the task. simple_console_debug_listener A debug listener that prints to the console. steam_kit_web_request_exception The error of a failed HTTP request. stream_helpers Async read/write helpers for tokio streams: little-endian numbers and
null-terminated strings. task_extensions Ignoring cancellation errors once a token is cancelled. utils Misc helpers: hex strings and OS detection. v_zip_delta_util Decompressing VZip deltas: VZip streams compressed against a previous chunk. v_zip_util Valve’s “VZip” container, used for Steam client updates and depot chunks. v_zstd_util Valve’s “VZstd” container, used for zstd-compressed depot chunks. value_stopwatch A tiny stopwatch. win32_helpers Windows helpers for the machine id: the boot disk’s serial number. zip_util Decompressing PKZIP archives with a single file, as older depot chunks use.
Reads the zip structures directly and inflates with flate2.
